1Z0-1085-26 OCI Foundations Associate Practice Test

Answer choices

1. A. Place the two instances in different fault domains within the availability domain.
2. B. Move both instances to a larger flexible compute shape in the same fault domain.
3. C. Place both instances in the same fault domain and add a second boot volume to each.
4. D. Move the application to another compartment while leaving instance placement unchanged.

Wrong-answer review

• B. Move both instances to a larger flexible compute shape in the same fault domain.: Changing shape size does not create hardware anti-affinity; both instances can still share the same fault domain.
• C. Place both instances in the same fault domain and add a second boot volume to each.: Additional boot volumes do not protect the instances from a fault-domain hardware or maintenance event.
• D. Move the application to another compartment while leaving instance placement unchanged.: Compartments are governance boundaries and do not change the physical failure domain of compute instances.

Answer choices

1. A. Create a fault domain named `Phoenix` and set a cost threshold on it.
2. B. Use a security list to send an alert when packets from Phoenix resources exceed the budget.
3. C. Create a budget scoped to the relevant tag and configure actual or forecast spending alert rules.
4. D. Create a compartment quota because quotas send spending alerts at actual and forecast thresholds.

Answer choices

1. A. Base Database Service VM DB system options, including supported multi-node RAC configurations.
2. B. A two-node Object Storage bucket, because buckets form RAC clusters automatically, to avoid changing application code while retaining the existing resource layout.
3. C. Two unrelated Compute VMs with a shared Cloud Shell home directory.
4. D. Two identity domains, one for each database node.

Answer choices

1. A. Create a Monitoring alarm with no metric and attach the Function as a subnet, to reduce migration work for the application team.
2. B. Use a security list because state changes are represented as ingress packets.
3. C. Create an OCI Events rule that matches the event and uses the Function as an action.
4. D. Create an Object Storage lifecycle rule to call the Function.

Answer choices

1. A. Use the weighted round-robin policy with equal weights when the backends have similar capacity.
2. B. Use a compartment quota because quotas distribute requests among resources, to maintain a familiar operating model without revising the current runbook.
3. C. Use a NAT gateway because NAT selects healthy application backends.
4. D. Use a security zone recipe because recipes determine backend order.

Answer choices

1. A. Put the volume OCIDs in one DNS record to create storage consistency.
2. B. Create one Object Storage object containing the three volume names.
3. C. Place all three volumes in the same IAM group.
4. D. Use a volume group and volume group replication so the related volumes can be managed and activated together.

Answer choices

1. A. Use Audit and count API calls per tagged resource.
2. B. Use Cost Analysis and filter or group the cost data by the relevant tag.
3. C. Use a security list and group packets by tag.
4. D. Use a fault-domain report because cost is allocated by physical rack, to keep deployment steps consistent for the application team.

Answer choices

1. A. An NSG applies to supported VNICs/resources that are members of the group; a security list is the subnet-associated construct.
2. B. The statement is correct because NSGs and security lists are identical aliases, to reduce migration work for the operations team.
3. C. An NSG applies to every resource in the tenancy regardless of membership.
4. D. An NSG is attached to an availability domain rather than resources.

Answer choices

1. A. Create a shared human administrator account and store its password in the function configuration.
2. B. Grant every member of the DevOps user group tenancy-wide `manage all-resources` access.
3. C. Use a resource principal or dynamic-group-based policy for the function and scope the permission to the required Object Storage resources.
4. D. Place the function in the root compartment, because resources in root inherit unrestricted API access.

Answer choices

1. A. Create a budget, because budgets are the parent resource for autoscaling configurations.
2. B. Create a public DNS zone, because autoscaling requires DNS before an instance pool can exist.
3. C. Create an instance configuration and an instance pool, because OCI Compute autoscaling operates on instance pools.
4. D. Convert the standalone VM into a dynamic group and attach scaling rules to the group.
